## What it is
A self-hostable web service for sending ebooks (EPUB, MOBI, PDF, TXT, CBZ, CBR) to a Kobo or Kindle ereader via its built-in browser using a unique key. It optionally converts EPUBs to Kobo EPUB (Kepubify) or Kindle MOBI (KindleGen) and crops PDF margins.

## Use cases
- send epub files to my kobo over wifi
- transfer ebooks to kindle without a cable
- self-host an ebook push service
- convert epub to kepub when sending to kobo
- convert epub to mobi for kindle
- crop pdf margins before sending to an ereader

## When to choose
- you want cable-free ebook delivery to a Kobo or Kindle using only the device's browser
- you want a self-hosted alternative to Amazon's Send-to-Kindle
- you need automatic format conversion (kepub/mobi) during transfer

## When to avoid
- you need a managed cloud service with no setup
- you want long-term storage or a library manager rather than transient transfer
- you cannot install external tools like kepubify or kindlegen
